Drone Keeper Mini, or other audible location device?

Has anyone used a Drone Keeper mini or similar? I'm reading about people losing their Karma in other peoples yards, high brush, etc. It seems to me an audible alarm would help these type of situations.

I have a tile slim stuck in the battery's plastic shell. My test results gave me a barely audible alarm (due to location of the tile) & shorter bluetooth range (also probably due to location). It alerted me when I was a few feet from the tile. With the tile in a wallet, I was in range yards away not feet. There was an update so I'll see how that improved the next day it isn't raining here in Florida.
